| description | The invention relates to a spindle device. A spindle device is provided with: a spindle having a tapered hole located at one end and to which a tool is removably attached, and a spindle cylindrical part located closer to the other end than the tapered hole and communicating with the tapered hole; a jaw chuck disposed in the spindle cylindrical portion and holding a tool; and a pull rod that is connected to the other end of the sleeve claw of the sleeve claw chuck and moves the sleeve claw chuck forward and backward in the axial direction of the main shaft, the sleeve claw chuck having a plurality of sleeve claw gaps that extend from one end of an annular sleeve claw forming one end toward the other end of the main shaft and that form a flow path that guides air to the taper hole. The main shaft cylinder portion has a receiving space for receiving the other end portion of the sleeve claw in the clamped state, the main shaft has a plurality of main shaft air supply paths for supplying air to the receiving space |
